Dyeing machine

ABSTRACT

A dyeing machine includes a machine base defining a cylindrical receiving chamber and a cloth passage for the circulation of a fed piece of cloth, and a jet nozzle upwardly mounted in one end of the cloth passage and adapted for ejecting a liquid coloring matter to dye the fed piece of cloth and to move the fed piece of cloth through the cloth passage.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a dyeing machine and, moreparticularly, to a simple structure of dyeing machine, which reducesfriction resistance to the fed piece of cloth, preventing damage to thestructure of the fed piece of cloth during dyeing operation.

[0002] A conventional dyeing machine is known comprising a machine basedefining a cylindrical receiving chamber and a cloth passage, a jetnozzle disposed in a horizontal position, an overflow nozzle disposed ina vertical position above the elevation of the jet nozzle, a first clothguide roller disposed in front of the jet nozzle and adapted for guidinga piece of cloth from the cloth passage over the jet nozzle into thecylindrical receiving chamber for dyeing, a second cloth guide rollersuspended above the overflow nozzle and adapted for guiding a piece ofcloth from the cloth passage over the overflow nozzle into thecylindrical receiving chamber for dyeing. This design of dyeing machineenables the fed piece of cloth to be circulated through the receivingchamber rapidly, and prevents the fed piece of cloth from beingwrinkled. However, the arrangement of the jet nozzle, the overflownozzle, and the guide rollers is complicated. When the piece of clothmoved over the cloth guide rollers, a friction resistance is produced tothe moving piece of cloth, and the cloth guide rollers may damage thestructure of the fed piece of cloth.

SUMMARY OF THE INVENTION

[0003] The present invention has been accomplished to provide a dyeingmachine, which eliminates the aforesaid problem. It is one object of thepresent invention to provide a dyeing machine, which eliminates the useof cloth guide rollers. It is another object of the present invention toprovide a dyeing machine, which uses the upward ejecting force of theliquid coloring matter ejected from the jet nozzle to move the fed pieceof cloth. According to one aspect of the present invention, the dyeingmachine comprises a machine base defining a cylindrical receivingchamber and a cloth passage for the circulation of a fed piece of cloth,and a jet nozzle upwardly mounted in one end of the cloth passage andadapted for ejecting a liquid coloring matter to dye the fed piece ofcloth and to move the fed piece of cloth through the cloth passage.According to another aspect of the present invention, the cloth passagehas a front end terminating in a smoothly arched front bent, which holdsthe jet nozzle for smooth circulation of the fed piece of cloth. Becausethe dyeing machine does not use any cloth guide rollers, all thedrawbacks seen in the aforesaid prior art dyeing machine due to the useof cloth guide rollers are eliminated.

BRIEF DESCRIPTION OF THE DRAWING

[0004]FIG. 1 is a plain view of a dyeing machine constructed accordingto the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0005] Referring to the annexed drawing of FIG. 1, a dyeing machine isshown comprising a machine base 1 defining a cylindrical receivingchamber 11 and a cloth passage 12. The cloth passage 12 has a frontinput end terminating in a smoothly arched front bent, and a rear outputend connected to one end of the receiving chamber 11. A jet nozzle 13 iscoupled to the front bent of the cloth passage 12 and arranged in anupwardly extended position. The input end of the jet nozzle 13 facesdownwards and aimed at the other end of the receiving chamber 11. Thus,the jet nozzle 13, the cloth passage 12, and the receiving chamber 11form a continuous cloth circulation path.

[0006] When a piece of cloth 2 fed into the machine base 1 of the dyeingmachine, it is circulated through the receiving chamber 11 and the clothpassage 12. When the fed piece of cloth 2 passes from the receivingchamber 11 into the cloth passage 12 through the jet nozzle 13, a liquidcoloring matter is ejected upwards from the jet nozzle 13 toward themoving piece of cloth 2 to dye the moving piece of cloth 2 andsimultaneously to force the moving piece of cloth 2 into the clothpassage 12. Because the invention eliminates the use of cloth guiderollers to guide movement of the fed piece of cloth, all the drawbacksproduced due to the installation of cloth guide rollers in the dyeingmachine are eliminated.

[0007] A prototype of dyeing machine has been constructed with thefeatures of FIG. 1. The dyeing machine functions smoothly to provide allof the features discussed earlier.

[0008] Although a particular embodiment of the invention has beendescribed in detail for purposes of illustration, various modificationsand enhancements may be made without departing from the spirit and scopeof the invention. Accordingly, the invention is not to be limited exceptas by the appended claims.

What the invention claimed is:
 1. A dyeing machine comprising a machinebase defining a cylindrical receiving chamber and a cloth passage forthe circulation of a fed piece of cloth, and a jet nozzle adapted forejecting a liquid coloring matter to dye the fed piece of cloth, whereinsaid cloth passage has a front input end terminating in a smoothlyarched front bent, a rear output end connected to an opposite end ofsaid receiving chamber; said jet nozzle is coupled to the front bent ofsaid cloth passage and arranged in an upwardly extended position, havingan input end downwardly facing an opposite end of said receivingchamber.
